b/w movie about a mermaid kuving in a fountain

As told to a psychiatrist: Mr. Peabody, a middle-aged Bostonian on vacation with his wife in the Caribbean, hears mysterious, wordless singing on an uninhabited rock in the bay. Fishing in the vicinity, he catches...a mermaid. He takes her home and, though she has no spoken language, falls in love with her. Of course, his wife won't believe that the thing in the bathtub is anything but a large fish.

A compilation of scenes from the mermaid movie series.

There's something in the water.

A boy and a girl draw pictures on the wall with sticks made of black fish. One day a blue fish drifts ashore to them.

The fisherman made his dream come true - he caught a beautiful mermaid. But it's not that simple.
